Sudan - Location, size, and extent
Situated in northeast Africa, Sudan is the largest country on the continent, covering an area of 2,505,810 sq km (967,499 sq mi), with a length of 2,192 km (1,362 mi) SSE – NNW and a width of 1,880 km (1,168 mi) ENE – WSW . Comparatively, the area occupied by Sudan is slightly more than one-quarter the size of the US. It is bounded on the N by Egypt, on the NE by the Red Sea, on the E by Eritrea and Ethiopia, on the S by Kenya, Uganda, and the Democratic Republic of the Congo (DROC), on the W by the Central African Republic and Chad, and on the NW by Libya.
The Anglo-Egyptian Agreement of 19 January 1899 established the parallel of 22° N as the international boundary between Egypt and Sudan. In 1902, however, a special administrative boundary was delineated between the Nile and the Red Sea, in order to facilitate the administration of nomadic tribes and to maintain the continuity of certain tribal areas in the border region. In 2001, the countries agreed to discuss the creation of an "area of integration" for this overlapping territory and both governments agreed to withdraw military forces from the region. The Egypt-Sudan boundary west of the Nile runs 892 km (554 mi); east of the Nile, the international boundary is 383 km (238 mi), and the administrative boundary is 357 km (222 mi). Including this administrative line, Sudan's total boundary length is 8,550 km (5,313 mi).
Sudan's capital city, Khartoum, is located in the northeast central part of the country.
